what happens in mac os x? you're assuming we should copy windows's behavior, why don't find a compromise of something to satisfy everybody? ctrl alt del should give me a restart or so, rather than a system monitor?

Andrea: In Mac OS X Ctrl Alt Del deletes the previous word -- but only because that's what Alt Del does, and the Ctrl is ignored. Someone using Ubuntu who types Ctrl Alt Del is far more likely to have previously used Windows than to have previously used Mac OS X, because (a) the combo does nothing special in Mac OS X, and (b) there are many more Windows users. And I don't understand how you think that restarting the computer would be a "compromise".

manny, Marco: Constructing a dialog specially for Ctrl Alt Del might make sense if it was a good keyboard shortcut in itself, but it is not, as even its inventor has pointed out. <http://www.youtube.com/watch?v=1zADyh0JQh8> The point here is not to emulate Windows, but to provide something that people pressing it are likely to be looking for, *without* adding extra interface surface area.

Valid points, but you're pointing out what "windows users" are expecting.

So in windows (since vista), the behavior is to offer a *few common options*.

Not saying we should offer "all" those options and clone their screen, but most likely the 2 or 3 that "different users" would be expecting.

Else this could become an endless discussion since from memory the behavior of this shortcut in Ubuntu has changed in almost every release...
Someone has always found that it needed to do something different. So maybe providing a dialog with more than one option would be the best solution for the majority.

Am sure microsoft has done quite a good amount of user/enterprise testing for choosing to provide that screen. So imho maybe some user testing would be needed here to offer the best choices.

I would love to see the system monitor get implemented in some way into the ctrl-alt-delete. It is a very comfortable and familiar way to access the system manager when an application freezes and your mouse cursor is trapped. (aka full screen flash)

Having a keyboard shortcut to access the system monitor is just good all around planning.

um , a way to kill resource hungry apps would had come in handy while testing precise. Firefox made the entire system go into a crawl multiple times on an atom netbook with 1gb ram (both unity 3d and 2d). Had to turn it off the bad way by pressing the button on the laptop.

@mpt; this is a user facing bug that affects user interaction with the Ubuntu 'platform', and as such this bug should be marked as affecting ayatana-design (see https://wiki.ubuntu.com/Unity/FilingBugs ). If you disagree with this process or with the definition of what Unity covers, please speak to Ivanka. We will also be discussing our design process as a group in the next few weeks, this will be the correct forum to discuss this issue.

I thought a while about the best solution for this problem and came up with this:

We can perfectly fix it without messing with Gnome itself:

First we will upgrade the Compiz Gnome Compatibility plug-in to also deal with other gnome shortcuts (currently it just deals with showMainMenu, showRunDialog, CommandScreenshot, CommandWindowScreenshot and CommandTerminal).

This will also have the positive side-effect that all will be perfectly configurable CCSM style, so the user will be easily able to modify everything to your needs if it won't suit him, it will be possible to not just change the shortcut, but also the command that is run, when hitting this key-combination.
The defaults will be the same as Gnome uses.

With another ubuntu-config.patch we will adjust the shortcut for Ctrl+Alt+Del to open gnome-system-monitor/processes tab instead of proposing a log out for Ubuntu/Unity only.

* Removed logic in the calculateWallOffset() function in the Expo
plugin that only accounted for offsetting the expo animation on the
left-most and top-most monitor. Also removed the
TestNoOffsetIfOutputIsNotOrigin test since this test is now invalid.
(LP: #1031710)
* Ctrl-Alt-Del should open the gnome-system-monitor at the processes
tab. This fix uses the commands plugin to override the default
action. This includes: - Install the commands plugin by default. -
Breaks/Replaces the compiz-plugins package for versions earlier than
0.9.10. - Patch commands.xml and integrated.xml to map gnome-system-
monitor to Ctrl-Alt-Del by default. - Start the command plugin upon
Compiz starting. (LP: #890747)

What a silly change, & by the way in windows ctrl+alt+delete open to 5 choices, the default being lock computer followed by, in order, - switch user, log off, change password & finally task manager.
Fortunately for most upgraders they'll never know you did this...

I'm testing a Live image of 13.10 and that shortcut still brings log out screen.

Everything related to Compiz and Unity is updated. Looking at the changelog of Compiz there should be two files presumably in /usr/share/compiz directory but I only have one commands.xml.

There's no sign of integrated.xml file even after installing compiz-plugins package. Looking at the contents of compiz-plugins-default package I also can't fing integrated.xml file. The commands plugin is enabled and the shortcut is set for command 20.

Something has changed in which Ctrl-Alt-Del can no longer be overridden by the Compiz Commands plugin, so bringing up the Gnome System Monitor at the processes tab using Ctrl-Alt-Del doesn't work anymore and instead the logout/lock dialog is brought up.

I guess Doug McMahon new something with his ominous message about most upgraders will never know this was done:/

1. The new shortcut to bring up gnome-system-monitor -p was not present in System Settings->Keyboard->Shortcuts.
2. The old shortcut in Keyboard shortcuts to use Ctrl-Alt-Delete to Log out was still present.

This probably causes confusion for users and is kind of a bad design. So I'm going to fix this for at least Trusty.

I will make a new shortcut in Keyboard->Shortcuts that sets Ctrl-Alt-Del to open gnome-system-monitor -p. I will also set Log out to Disabled. This way, it is clear to the end user what is going on here and is also quite easy to set Ctrl-Alt-Delete back to Log out or something else entirely.

What I need to do is ask Design which heading they want the new shortcut to be under and what they want the wording to say.

* When static switcher is enabled and has an option to show
application icon turned on the icons are expected to be ~1/3 of a
thumbnail (48px). Instead they are displayed in 512px size and
completely cover everything. This change addresses this issue. See
LP #1173914. (LP: #1173914, #1186426)

* Replace <Primary> with <Control> in CCSM. Fixeshttps://bugs.launchpad.net/compiz/+bug/1069121. (LP: #1069121)
* Tweak support of key bindings of the form
'<Modifier>Modifier_KeySym'. We tweak a bit the behaviour of key
bindings such as '<Control>Shift_L' and '<Alt>Alt_R'. 1. We ignore
the order of key pressing and releasing, so tapping
'<Shift>Control_L' is the same as '<Control>Shift_L'. 2. We properly
handle the double modifiers case, for example '<Control>Control_R'.
3. We also parse key bindings with '<Primary>' being equivalent to
'<Control>'.
* Fix GSettings tests with extra slash.
* Add an interface for plugins to provide non-option key actions that
can be triggered.
